So, I was looking at shield energizers, and I was thinking: Why couldn't we crazy-ass experimental biotics modules that immensely help in some ways, but hurt in others?

Here are some random thoughts (Obviously, they'll boost their stats more than standard modules):
Experimental Kinetic Catylizers: increase sprint speed, but lowers stamina and (possibly) stamina regen (burns you out)

Experimental Myofibril Stimulant: increase melee damage and jump height, but lowers armor and stamina regen (the increase in strength takes quite a toll on your muscles- you have a difficult time recovering from strenuous activity, and your dropsuit's nanites must focus on repairing muscle mass)

Don't really have anything for cardiac regs atm. Might think of something.

Along with that, how about a biotic to increase reload speed and/or grenade range?

Just throwing **** out there to see if anything sticks.

Its an idea but picking a specific fit allready makes you less powerful in other specialized fits.

If i choose a shield setup with a RR I'm better at range then I am in CQC. doing this with biotics may make for unfair gameplay.

your example shows myofibril stimulants increaseing melee damage for lower armor and stamina but a cloak will still fix the weakness in armor because they can't shoot you.

you could dive into a group of heavys, one hit each with no charge up and jump away and cloak again. sounds balanced?
